The anatomic coracoclavicular ligament reconstruction (ACCR) is a surgical procedure to address acriomioclavicular joint instability. The coracoclavicular ligaments are reconstructed using a semitendinosus allograft passed beneath the coracoid and through bone tunnels in the clavicle.
Where is the CC ligament?
The coracoclavicular ligaments are strong supports between the lateral end of the clavicle and the coracoid process of the scapula. On each side, they are sited medially and inferior to the acromioclavicular joints.
When describing the ACCR anatomic coracoclavicular reconstruction technique What is the distance from the distal clavicle to the tunnel placement for the graft?
A Drill Tip Guide Pin is used for placement of the tunnels. The first tunnel is for the conoid ligament, and that is roughly 45 mm away from the distal end of the clavicle in the posterior one half of the clavicle.
What is the acromioclavicular ligament?
This ligament is a quadrilateral band, covering the superior part of the articulation, and extending between the upper part of the lateral end of the clavicle and the adjoining part of the upper surface of the acromion.
What is Coracoacromial Arch?
Coracoacromial arch is an osteofibrous structure resulting from the continuity of the acromion, coracoacromial ligament, and coracoid process with each other (13). In case of lower localization of coracoacromial arch, the pressure on the rotator cuff may increase (13).
What is anatomic Coracoclavicular reconstruction?
The anatomic coracoclavicular ligament reconstruction (ACCR) is a surgical procedure to address acriomioclavicular joint instability. The coracoclavicular ligaments are reconstructed using a semitendinosus allograft passed beneath the coracoid and through bone tunnels in the clavicle.
What is a CC joint?
The coracoclavicular ligaments (CC) complex consists of the conoid and trapezoid ligaments. They insert on the posteromedial and anterolateral region of the undersurface of the distal clavicle, respectively. It mainly serves to provide vertical stability.
What is the trapezoid line?
Trapezoid line or ridge (Linea trapezoid) is an elevation that runs obliquely from the conoid tubercle to the lateral end of the clavicle. It serves as an attachment point for the trapezoid ligament, which is also a part of the coracoclavicular ligament mentioned above.
What is the function of costoclavicular ligament?
The costoclavicular ligament or rhomboid ligament (a.k.a. Halsted’s ligament 2) is the major stabilizing factor of the sternoclavicular joint and is the axis of movement of the joint.
Does a Grade 3 shoulder separation require surgery?
Most people do well without surgery. The severe injury (Grade 3) can be treated either nonoperatively or operatively. Non-operative treatment involves immobilisation in a sling for two to three weeks followed by a course of physiotherapy.
Will AC joint bump go away?
The ligaments heal in this position, so the bump does not go away. It is possible to have surgery to correct the bump. But normal shoulder function will usually return even without surgery.
How can I prevent my AC joint from dislocating?
Whereas the majority of AC joint dislocations can be treated nonoperatively with a trial of immobilization, pain medication, cryotherapy, and physiotherapy, there are patients that do not respond well to conservative management and may require surgical treatment.
What are 3 main ligaments that make up the acromioclavicular joint?
Acromioclavicular (AC) joint
| Type | Synovial plane joint; multiaxial |
|---|---|
| Ligaments | Intrinsic: Superior acromioclavicular ligament, inferior acromioclavicular ligament Extrinsic: Coracoclavicular ligament (with conoid and trapezoid parts) |
| Innervation | Lateral pectoral nerve, suprascapular nerve |
Do AC ligaments grow back?
Or the ligaments that support your AC joint may be repaired. A ligament from another part of your body may be used to repair it. Your end result may also depend on the severity of your injury. Most people will get back all or almost all normal arm and shoulder function, but a slight deformity may remain.
What is glenohumeral ligament?
Glenohumeral Ligaments (GHL): In the shoulder, the joint capsule is formed by a group of ligaments that connect the humerus to the glenoid. … They are the superior, middle and inferior glenohumeral ligaments. They help hold the shoulder in place and keep it from dislocating .
What is the Musculotendinous cuff?
: a supporting and strengthening structure of the shoulder joint that is made up of part of its capsule blended with tendons of the subscapularis, infraspinatus, supraspinatus, and teres minor muscles as they pass to the capsule or across it to insert on the humerus. — called also musculotendinous cuff.
What movement does Coracoacromial ligament limit?
Simply by its position anterosuperior to the glenohumeral joint, it passively restricts upward displacement of the humeral head.
What is the purpose of the coracohumeral ligament?
The coracohumeral ligament is a broad ligament which strengthens the upper part of the capsule of the shoulder joint.
What is a Coracoclavicular joint?
Coracoclavicular joint (CCJ) is a rare anomalous joint occasionally found between the coracoid process of scapula and the conoid tubercle of clavicle. The articulation has been extensively studied by means of anatomical, osteological and radiological investigations.
What is the CPT code for coracoclavicular ligament reconstruction?
Wide draping is used so the distal clavicle and the AC joint area are free and accessible. CPT Code: 23550—Open treatment of acromioclavicular dislocation, acute or chronic.
How do you pronounce Coracoclavicular?
Is AC joint surgery worth it?
What are the results of AC joint surgery? Most patients get excellent pain relief with this operation, and nearly 95 percent return to their preinjury level of activity and sports. There are few complications and most patients are very satisfied with the result.
What can I expect after AC joint surgery?
After surgery, patients can expect to wear a sling for about four weeks and lower arm exercises may begin immediately after the two to three weeks immobilization. Most rehabilitation programs will begin after the sling is removed and will at least 6 to 8 weeks to regain full motion of the shoulder.
Can a separated shoulder heal on its own?
A minor separation usually heals within a few weeks. A more severe separation might take several weeks to months to heal. You might always have a noticeable bump on the affected shoulder, but it shouldn’t affect your ability to use that shoulder.
What does the trapezoid ligament attach to?
The trapezoid ligament arises from the upper surface of the coracoid process. It attaches to the trapezoid line (or ridge) on the inferior surface of the clavicle. The anterior border of the trapezoid ligament is free. The posterior border attaches to the conoid ligament.
What is the clavicular notch?
Medical Definition of clavicular notch : a notch on each side of the upper part of the manubrium that is the site of articulation with a clavicle.
What type of bone is trapezoid?
The trapezoid bone (lesser multangular bone) is a carpal bone in tetrapods, including humans. It is the smallest bone in the distal row of carpal bones that give structure to the palm of the hand.
What is the impression for costoclavicular ligament?
On the inferior surface of clavicle near the sternal end is a broad rough surface, the impression for costoclavicular ligament (costal tuberosity, rhomboid impression), rather more than 2 cm. in length, for the attachment of the costoclavicular ligament.
Can the clavicle rotate?
When the arm is raised over the head by flexion the clavicle rotates passively as the scapula rotates approximately around 40-50degrees. This is transmitted to the clavicle by the coracoclavicular ligaments. this movement is allowed by the relative slackness of the ligaments in this position.
What is another name for the clavicle?
Clavicle, also called collarbone, curved anterior bone of the shoulder (pectoral) girdle in vertebrates; it functions as a strut to support the shoulder.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
